Неопределенный метод "изменить порядок" для #используя ActiveAdmin

У меня проблема с ActiveAdmin, использующим Ruby ruby ​​1.9.2p290 и Ruby on Rails 3.2.1.

Я использовал эту вики-страницу для настройки ресурса AdminUsers, который работает отлично: Your FirstРесурс администратора: AdminUser

После этого я хотел создать ресурс для моей модели проекта.Миграции для этого выглядят так: 

class CreateProjects < ActiveRecord::Migration
  def change
    create_table :projects do |t|
      t.string :name
      t.text :description
      t.boolean :isactive

      t.timestamps
    end
  end
end

class AddSlugToProjects < ActiveRecord::Migration
  def change
    add_column :projects, :slug, :string
    add_index :projects, :slug
  end
end

Модель моего проекта: 

class Project < ActiveRecord::Base

  scope :isactive, :conditions => ["isactive = ?",true]

  extend FriendlyId
  friendly_id :name, use: [:slugged, :history]

  attr_accessible :name, :description, :isactive

end

И это контроллер проекта: 

class ProjectsController < ApplicationController

  def index
    #
    # @projects gets filled in application_controller to be always
    # available for the twitter bootstrap navbar
    # @projects = Project.isactive.find(:all, :order => 'LOWER(name) asc')
    #
  end

  def show
    @project = Project.isactive.find(params[:id])
    if request.path != project_path(@project)
      redirect_to @project, :status => :moved_permanently
    end
  end

end

Администратор / projects.rbв настоящее время 'пусто' 

ActiveAdmin.register Project do  
end

И после всего, что я получаю, это следующая ошибка:

И я понятия не имею, в чем проблема ...

Ах, я нашел решение. Я не знаю точно, почему произошла ошибка, но мне пришлось изменить свой application_controller.

В application_controller я загрузил все проекты в @projects: 

before_filter :getActiveProjects

protected

  def getActiveProjects
    @projects = Project.isactive.find(:all, :order => 'LOWER(name) asc')
  end

Это сбивало с толку ActiveAdmin. После того, как я изменил это на 

before_filter :getActiveProjects

protected

  def getActiveProjects
    @projects_all = Project.isactive.find(:all, :order => 'LOWER(name) asc')
  end

и действие индекса_проектов_контроллера на 

def index
  @projects = @projects_all
end

все работало нормально;)

Более простое решение - просто пропустить фильтр в конкретном активном административном контроллере: 

ActiveAdmin.register Project do  
    controller do
      skip_before_filter :getActiveProjects
    end
end

Активный администратор производит специальную обработку @resource переменных. Где resource - соответствующее имя класса, переданное методу регистрации. Так для кода: 

ActiveAdmin.register Project do  
end

имя переменной 

`@project`

Мы не должны присваивать значение переменной с таким именем. Также такие переменные могут быть объектом класса ActiveRecord :: Relation. И то, как @Oliver пишет имя как @projects_all - хороший выбор. Использование skip_before_filter также решает проблему.

Одну хитрую вещь нужно проверить. Контроллер ресурса может не иметь никаких фильтров. Контроллер ресурса может вообще не существовать. Какое имя фильтра нужно поместить в skip_before_filter? А где такие фильтры? Контроллер приложения по умолчанию используется в любом случае. Фильтр может быть установлен на главном контроллере приложения. Сообщение об ошибке этой проблемы вообще не информативно. Поэтому необходимо проверить контроллер приложения на наличие установленных фильтров.
